Description

  The present invention relates to a voice azimuth identification system, which functions by an automatically controlled voice generation and verbal communication device through a wireless computer in a mobile phone or a WLAN network, integrated with a communication machine position identification and voice azimuth identification system, The present invention relates to a system for navigating pedestrians outside or inside a facility such as a station or other location, ie, a voice orientation identification system integrated with a communicator location and voice orientation identification system.

  With regard to functions and services provided in public or private places such as subway and railway stations, there is no real information that is normally available to blind or visually impaired people.

  With few exceptions, Braille information bulletins found at some transportation stations, voice explanation systems, also called voice guides, that work with specific players, such as those rarely seen in museums, and standardization in the future. is necessary. There is also a tactile floor system that is very rarely seen or partially introduced in transportation stations and public pedestrian roads. Finally, there is also an information system based on verbal messages to call attention or provide direct information, generally related to emergency evacuation signals, airport security and “gap attention” type alarms on the London Underground is there.

  However, the orientation and navigation information that is essential for users to fully use the service in transportation or public or private places is wide and complex. For example, in the case of transportation facilities, information on destinations, stations, and routes can be obtained. However, operation schedule information and fare information regarding transportation vehicles, ships and possible destinations are also required.

  Other necessary information that enables the use of the service is generally provided visually and is installed in different parts of the station and other buildings, so for obvious architectural reasons, everything in a building It may not be visible from the point. This is the case at the ticket office. This is also true for other essential or important services such as restrooms, police or guards, medical offices, telecommunications rooms, emergency equipment, emergency exits, etc.

  This is also the case for important information about personal navigation that is necessary for people to reach their destination, namely a boarding slope, a subway platform or any stop. In other words, it is information about a personal route. Much of the above information is called signaling, which is not available at the entrance of buildings or facilities or access passages normally used by passengers or other people, but gives directions and describes the services available to the user More visual support means are introduced. In places with various subspaces and rooms, some signs and other visual information cannot be visualized. Therefore, in order to facilitate navigation, the position where the signboard should be installed is sufficiently investigated. In more complex buildings, information on all services and places such as doors, elevators or stairs is required.

  For customers who are blind and visually impaired as customers, if the above information including navigation information is easily provided, there are severe restrictions in using domestic and foreign transportation facilities and other facilities and services.

  When trained under a supervisor, it is generally known that blind or visually impaired persons can use their own means to use internal and external transportation stations or other buildings and services as described above. It has been. However, restrictions on obtaining information remain the same. In such situations, blind or visually impaired people are severely limited in their rights as citizens and as users / customers of certain services.

  Audio signals and acoustic lights are used to provide navigation information for blind or visually impaired people on the street, for example, audio signals attached to traffic lights. Such a traffic light, that is, a signal light with sound, operates autonomously in synchronization with the traffic light. The main drawback is noise pollution. So far, the sound amplitude control device has been used in consideration of the operating time of the day and the level of environmental noise, and natural sounds such as bird calls have been adopted. Has been eased by.

  There are several patent applications that propose navigation assistance systems for blind people.

  The document of Canadian Patent No. 10107684 entitled “Management and Navigation System for the Blind” describes the use of unique identification equipment using radio waves, such as “RFID tags”. A cane or signal reader attached to the person's leg is signaled through the communication module to signal the route. In this document, the location unit may locate and track the location of the communication module using infrared radiation or sound waves. A microphone embedded in the communication module is used to collect acoustic waves emitted by the user himself / herself or other persons and / or acoustic waves emitted by the audio or ultrasonic acoustic localization device. A processor processes the voice collected by the microphone and sends the processed data to a computer system or communication module, where the data is further processed. A speaker embedded in the communication module is used to generate warning signals, explanations and other information. Use a microphone and speaker at the same time as an acoustic tracking device to locate the user using acoustic waves that allow the microphone or speaker to communicate with other sound sources or sensors installed in the building or outdoors Can do. The feasibility of using the acoustic localization method disclosed herein without using human hearing is very suspicious in real-world environments, because the nature of the acoustic wave is different, so that tracking devices This is because significant interference occurs and the low frequency hinders effective speech coding in a way that can be handled by display processing techniques and is not fast enough to be beneficial during user route determination.

  In the document of European Patent No. 1930742 entitled “Navigation device and navigation system and navigation method for the blind and visually impaired”, the GPS system is used for navigation of the blind. A mobile phone equipped with a wireless technology interface may be used. This system has various obstacles in use because there is no GPS or similar signal reception area in a building or other facility. Establishing a route with an accuracy of 0.5 m is not feasible in practice, especially in outdoor environments, due to the well-known phenomenon of “fading” or “multi-propagation”. This system is very similar to that developed in an EU-funded project called MORE until 1977, the first mobile phone with a differential GPS that enables tracking and navigation by the disabled. GSM + GPS was produced.

  Finally, Korean Patent Application Publication No. 20070089263 entitled “Navigation System for the Blind and Mobile Device With It” is a GPS-based system that communicates with the blind by highly embossed lettering or voice. Is disclosed.

European Patent No. 1930742 Korean Patent Application Publication No. 20070089263

  The present patent application overcomes the aforementioned problems. The sound source used in the present application can be listened to using a device that allows the user to specify the position of the sound source directly or with his / her ability. Orientation identification is accomplished using a normal sound source that is selected so that people can distinguish the sound source from other environmental sounds and noises, especially in indoor or outdoor environments that are subject to reverberations and sound reflections.

  On the other hand, the new system utilizes acoustic orientation, but GPS signals can also be used as a tracking system.

  To allow access to critical information and personal orientation and navigation by the blind or visually impaired, it is necessary to use one or more alternatives that can replace visual information.

  To fully resolve the main problem of accessing the service and information about the building or other facility where the service is provided and making the information available to the blind or visually impaired and others Requires the integration of information and navigation resources into one realistic and simple system. In this sense, the present application proposes the use of a wireless personal communication device. The description disclosed herein proposes to use a network that covers a specific location where service is provided and where the use of information is needed, along with other networks that have general coverage.

  The following description is made with reference to the accompanying drawings, which illustrate preferred implementations of the present application, but are not intended to limit the scope of the invention.

It is a figure which shows a system architecture. It is a figure which shows one specific application example of this invention.

  Personal communication devices, also called mobile terminals, are used for mobile communication of voice or data through a network of dedicated base stations, such as Global System for Mobile Communication (GSM), Personal Communication System (PCS), or Universal Mobile Telecommunication System (UMTS). It can be a mobile phone as used. However, as long as two-way communication by voice is possible, any other type of wireless communication device can be considered for use in the present application by making necessary adjustments to the system. It is an important feature of the present invention that it utilizes a local network in which commercially available conventional types of elements are distributed.

  Can be used with any type of local wireless network, and the radiation used can reach all points of the location without problems, allowing for proper coverage and human communication between the mobile device and the network infrastructure Have the bandwidth to Another feature realized by a suitable local network that is part of the present invention is the ability to provide location of the mobile terminal, as will be described later.

  In addition to voice communication functions, the communicator may have other human interfaces that can activate or disable voice communication tools and simple information transmission via a standard telephone keyboard. .

  The second element of the present invention is a system of sound generators or sound generators such as loudspeakers or “buzzers” that are assembled in a building or facility according to the user's orientation specific purpose. Voice orientation identification is a natural human ability associated with the ability to determine the source and direction of sound. Research has been published on the use of human hearing to locate sound sources and their use in virtual reality environments. Headphones can be used to simulate the source and direction of sound. However, the use of headphones impairs the mobility of blind or visually impaired people in the real life environment, because the headphones cannot hear the environmental sounds that are essential for identifying their orientation. In the present invention, a thorough test was conducted to characterize the human voice orientation capability in indoor and indoor environments. As a result, it was found that the best average quality was related to the orientation of the punctual sound source. The localization of the sound source was analyzed both in azimuth and in altitude change. At the same time, we selected the type of sound that should be used for human orientation, and concluded that the most effective and preferred sounds are transitional sounds and broadband sounds, such as chirps, short noises or vibration sounds. . From the research conducted, the present applicant confirmed that the human voice direction specification of the present invention is feasible. We also analyzed the dynamic use of point sound sources to identify the direction in which the user moves and approaches the sound source, and confirmed its usefulness in the situation of this application.

  For people without visual impairment, in addition to audible sound waves, the idea of providing a spatial reference point on demand at the exact moment, as proposed in this application, uses other means besides speech, That is, it can be realized by using visible light instead of the sound source.

  In the present invention, the use of the sound source for direction determination during route determination is completely controlled by this system. The determined voice is automatically activated only when the system determines that it is appropriate for correct guidance and navigation while following a route previously established by the user's request. Depending on the natural environment of the location or the characteristics of the building and the proximity of the target point acoustically indicated by the signal, one sound source may be omnidirectional and another sound source may be directional. May be.

  The third element of the present invention is a Bluetooth and / or Wi-Fi and / or other mobile phone or wireless communication network system implemented in and related to the location of interest. This is the local wireless network described above. This is a network built using technologies available on the market. Through this network, the mobile terminal can access the system and use the communication channel it provides. The position of the mobile terminal is generally secured by the same network. It can also be secured by specific networks based on different types of technologies if it is convenient. The connection between data access points (DAP-data access points) of this wireless local network is secured by Ethernet® or other wired network or another wireless network for transmission only. This transmission network is managed by a conventional “switch”. The wireless network can be designed to ensure a continuous “seamless” mobile phone reception functional area, or it can be composed of a set of separate cells with non-overlapping coverage areas. In the former case, the system works by “switching” the cells. In the latter case, the system operates intermittently and is a continuous process by the central system.

  The present invention is also based on the location of the user's mobile terminal. The location system is the fourth element of the present invention. This is external and available on the market. In order not to compromise the security of the system, information about the position of the mobile terminal should be supplied with sufficient accuracy. There are systems based on the collection of information about characteristics of signals received from data access points or network nodes by a mobile terminal. Other systems are based on information collected by the wireless network regarding signals generated by mobile phone terminals. The basis of these techniques is the recognition of the radiation field pattern at that specific location. This element ensures that geographically determined information is supplied, and this information is used to determine the actual route status of the user and his mobile terminal. In some cases, the mobile terminal for the purpose of specifying the position may be different from the mobile terminal for the purpose of communication. As technology advances, the market tends to offer more integrated radio interfaces on a larger scale. It should be noted that a tag (TAG) type device or a bracelet can be used instead of the mobile terminal.

  The identification of the mobile terminal is inherently related to the location specification. Therefore, the above-described elements enable accurate identification based on codes of a conventional nature in the system, such as a medium access control (MAC) address, or a unique identification password.

  User automatic location can be performed by GPS, other GNPS, WLAN, or in WMAN or another cellular network. It can also be performed by infrared rays, ultrasonic waves, or RFID (Radio Frequency Identification).

  The fifth element of the present invention is an operation control and user interaction management system. This system is based on a collection of computers connected to a network. The network may be Ethernet type, wireless, or the Internet as long as a short waiting time can be secured so that the system can operate without delay. Examples of system operation include interactive help desk telephone service and route determination service using dynamic information. Users can use the service by dialing a short phone number in the local or global network. When the mobile phone terminal is connected to the network, the system automatically displays the words on the startup screen, introduces the system itself to the user, and explains the first operation method. In other cases, the system can alert the registered user by phone and inform the user of the new information just displayed on the train station or boarding deck screen. Operation is assured by commercially available interactive management software of the Interactive Voice Response (IVR) type. At the same time, the other two types of software ensure telephone service / call management and a wireless communication path and information service. The dialog management system also queries the location device described above during the route determination of the user and sends instructions for the guidance voice system production component described above.

  The dialogue management system allows users to have a clear and concise dialogue and have a reliable and reliable usage experience, sending confirmation at key points in the decision-making process and during route determination / navigation. Designed to be able to listen to others. This system has a dedicated memory for each user, the user can reuse the information from the past route according to the user's request, and different types according to the individual purpose. When a dialog is used, that is, when a user's behavior can be predicted, a specific step can be omitted. Whenever a call is interrupted for any reason, the system can resume the conversation from the point of interruption in the next call if the user chooses. The dialogue system functions by the voice communication system of the mobile phone terminal through the text-to-speech (TTS) of the synthetic conversation conversion module. Phrases are concise and clear and are carefully selected to be understood by as many people as possible. For data entry and user command, the present invention provides two systems: an automatic speech recognizer (ASR) with independent speakers and a two-tone multi-frequency keystroke recognition system (DTMF (dual-tone multi-frequency-frequency). )) In parallel. Such parallel usage allows users to use their voice to interact with the system, or may choose from mobile phone keys, such as when the user needs privacy, etc. This is very useful in noisy situations where speech recognition is difficult.

  The above phone service ensures that calls received by the system are managed from the beginning, the access permission of the user's mobile terminal is confirmed, the data flow during the call is managed, and the call is included in the dialogue management system. When the order arrives, it is reliably transferred to the trunk channel ready to take multiple calls at the same time. This service is fully executed by PBX (Private Branch Exchange) type software, and its operation is supported in a computer network that is part of the operation management and user interaction management system. Currently, the telephone system employs a telephone protocol called VoIP (voice over internet protocol) and SIP (session initiation protocol).

  The telephone system can be divided into at least two subsystems. The first is for the local network, and the second is for universal access by public telephone system or global coverage telephone system. The first subsystem connection is established by the local computer network, while the second subsystem connection is through a conventional digital telephone access gateway for VoIP / SIP. Whenever a call to the system is made through the global telephone system, for example on the ground or in a mobile network, these telephones are served by a second telephone subsystem, mainly for guidance in outdoor spaces in public places Along with the content, it is sent to the dialogue management control system sector to enable the user's movement plan and actual movement to the destination. Due to the function of such a system, the entire city becomes an information provision range. In order to achieve orientation and navigation in outdoor public routes, the system tracks users using GPS (Global Positioning System), etc. attached to and incorporated in mobile phone terminals, Geographic coordinates and other relevant information can be transmitted. Alternatively, the user can provide the system with geography or street information that allows the person to be located within the city-wide georeferencing system. For example, the user supplies information regarding his / her destination to the dialog management system by voice or DTMF. From this point, the system generates a pedestrian or mixed route (if other modes of transportation are involved). This route is calculated in an appropriate manner and communicated to the user, who can save it for later use. This orientation specification and user navigation in a space not covered by the local navigation network can be performed by other tools such as an electronic compass attached to the mobile phone.

  An additional point to note is that the interconnection between two telephone subsystems over the Internet or an intranet allows for route planning for the entire city and local guidance at the locations of interest, allowing users to Guidance and direction identification system for sufficient support is available. At the location of interest, the system can provide guidance in sufficient detail to indoor or interior spaces where a system such as a GPS cannot operate with reasonable stability. In conclusion, the present invention is a navigation and guidance system that can be used in indoor and outdoor spaces. Another feature of the present invention that differs from the current technology is that in some GPS navigation systems, an extrapolated guidance method for outdoor spaces performed by an electronic compass and gyroscope is used in an indoor environment to determine the route by a pedestrian. The point is that the local guidance system can be sufficient to operate.

  The information service described above is an important part of the present invention. This is because all of the information about the location of interest depends on the information service, the use of the system and the history and record of user information. This service is designed in the form of a complex database accessible through a local computer service or Internet web service, and is managed by a local or Internet portal.

  Places of interest include public transport stations, public transport vehicles, shopping centers, cultural, educational or leisure facilities, government buildings, hospitals, military bases or courts, or other indoor or outdoor social, A space of economic or administrative nature.

  In the case of an information service for a transportation system, for example a subway, the system informs the user about subway station information, whether these stations are underground, on the ground, their internal functions or interests. Locations such as ticket offices, ticket gates, cafeterias, restrooms, exits and subway maps. For subway maps, it is necessary to display information such as subway lines, train stations, operation schedules, required times, fares, ticket types, and boarding information.

  With regard to information necessary for creating a map of a point of interest, the information system provides information necessary for user guidance or navigation planning in real time.

  The above-mentioned Internet portal allows you to manage the entire system through a management web page, showing numerical values of significant changes in system operation locally or from a remote location. And interventions can be applied. The portal also allows you to access the system's database records and update them manually or automatically.

  FIG. 1 shows the architecture of a system according to the invention. Basically, this shows how a conventional GSM mobile phone can be used to access information from outside or inside a specific public location such as a subway station. Through access to mobile phones equipped with Bluetooth (BLT), Wi-Fi, etc., specially designed for this purpose, users can, for example, get local information on subway stations and how to get inside It is possible to use the voice assistance with the help of a mobile phone for specifying the direction and navigation when walking in a subway station. Users can also access operation information by connecting to a voice portal.

  Two complementary and complex systems, namely, non-disturbing, separate voice systems and locations of interest to the user, to identify the direction within the train station and aid navigation, A Bluetooth mobile phone system associated with the is created.

  The sound system is based on voice “signals” or “buoys”, which are encoded and carefully positioned in the access location or some area of the subway station, through the location and space of the voice, or where the user wants to reach or Assist users in navigating to their destination and determine their heading.

  This information includes voice information provided by the mobile terminal (cell phone with BLT or Wi-Fi), which allows the user to combine his two information tools that he can use in his station in the station. Identify and navigate directions. Telephone communication can be performed using the VoIP / SIP protocol.

  The Bluetooth mobile phone is configured by a Bluetooth Data Access Protocol (DAP) connected to a special server in the station premises through Wi-Fi or Ethernet, which can access the Interactive Voice Response System (IVR). The interactive content of this system is contextualized to the specific part of the station where the user is.

  Information is “piconet” that is temporarily formed on the user's mobile terminal (BLT or Wi-Fi mobile phone) as soon as the user approaches the access point (distance is 10 to 100 m depending on location) Through the access point control device. To obtain the information, the user is individually informed of the availability of the information (by vibration or call), and the user can connect to the interactive system by simply pressing the keyboard of the terminal as desired. Can be enabled.

  Access points such as BLT or Wi-Fi data can be used by existing blind people or visually impaired users to choose where they need to go within the station and to use the necessary services. It is installed in a place where it is determined that it is necessary to access information in a form instead of information (for example, ticket office). The wireless communicator may be of the Bluetooth, IEEE 802.11, Wi-Fi or HiperLAN, DECT, CDMA or OFDMA e SOOFDA, IEEE 802.16, WiMAX type.

  Obviously, blind users are free to use other physical access support tools, such as braille blocks, braille signals and general audio information provided on the floor.

  At the same time, a system that can reliably provide information services outside the station can be developed, or in other locations that employ BLT, the coordination between the two systems can be reliably performed.

  The above-mentioned system can also be based on visual information about identification elements properly located at access points in public areas to help users locate voice communications or terminal keyboards or orientations. It can be applied to people who do not have visual impairments when it is performed through the interface device.

  A specific application example of the present invention will be described below with reference to FIG. It can be seen that in the space of interest (20) is the location of interest (5), in this case the elevator door that the user (1) is going to go. In the space of interest (20) is a wireless network (6) that is configured through a switch (7) and brings together one or more data access points (4). This wireless network is a PBX (10) between a user (1) terminal (2) and a system implemented on one or more computers (9) built on a local network (8). ) To control voice communication or DTMF. Alternatively, voice communication can be performed over another private or public wireless channel. With this system, the terminal location (2) of the user (1) can be continuously obtained through an IVR (Interactive Voice Response) module (11) through a wireless network and finally in combination with the tracking module (12). Done.

  The operation of this system is controlled by the IVR module (11), which performs an automatic interaction with the user (1), in which the module informs the user at the location of interest (20). Provide accessibility options and / or personal navigation assistance. In order to make the information freely available to the user, the system is distributed if it has a local service module or is connected to the Internet (19), and this distribution is supported by the router (18). In addition to voice communication performed through the terminal (2) in the personal navigation process in the space (20) of interest supported by the present invention, the user (1) controls the IVR at each moment ( 11) under the space of interest (20) enough to show the user (1) the exact location of the place of interest (5) and to navigate the user towards it The sound signal is received from the source such as the speaker (3) installed after investigation. The sound generation of the loudspeaker (3) is performed on a well-studied sound selected according to the human hearing ability in voice identification and localization and under the full control of the IVR module (11). The sound module supplies the electrical signal of the sound it generates to the amplification system (16) attached to the network of sound sources (17), and in all acoustic spaces at that time One or more sound sources can be activated.
